Quill with Integrated Flow Limiter

摘要

A high-pressure quill for a fuel injection system of an engine includes a pair of elongated components linked together in fluid communication. The upstream component includes a plenum chamber with a seat at its upstream end. The pair of elongated components is linked together by a linking component in a manner to permit fluid flow therethrough. A fuel flow limiter is slidably supported in the chamber and is operable during normal operation to provide predetermined quantities of fuel during each injection event to a combustion chamber and, in the event of a failure condition, to terminate fuel flow.
